Neoarchean granite-greenstone belts and related ore mineralization in the North China Craton: An overview
TL;DR: In this paper, the amalgamation of microblocks welded by 2.75-2.6-Ga GGBs is correlated with the upwelling mantle plume with eruption close to the continental margin within an ocean basin.
Journal ArticleDOI
The detrital zircon record of an Archaean convergent basin in the Southern São Francisco Craton, Brazil.
TL;DR: In this article, the authors combine field observations and in situ U-Pb/Lu-Hf detrital zircon analyses to constrain the evolution of a large, ancient convergent basin in SE Brazil.
Journal ArticleDOI
Qingyuan high-grade granite–greenstone terrain in the Eastern North China Craton: Root of a Neoarchaean arc
TL;DR: The Qingyuan terrain represents remnants of the root of a Neoarchaean arc: its anticlockwise P-T-path recorded the initiation of the arc to its cession and exhumation/cratonization at ~

TL;DR: The Tsawela Gneiss (TG) is a well-preserved coarse-grained diorite to tonalite suite within the ancient gneiss complex of Swaziland, eastern Kaapvaal craton.

A 2.5 Ga fore-arc subduction-accretion complex in the Dengfeng Granite-Greenstone Belt, Southern North China Craton
Hao Deng,Hao Deng,Timothy M. Kusky,Ali Polat,Ali Polat,Chen Wang,Lu Wang,Yunxiu Li,Junpeng Wang +8 more
TL;DR: In this article, the Dengfeng granite-greenstone belt (DGGB) is interpreted to have formed in a fore-arc tectonic setting, which is related to the suture zone of ca. 2.5 Ga arc-continent collision between a TTG-dominated arc terrane in the COB and the Eastern Block of the NCC.

Orogenic Andesites and Plate Tectonics
TL;DR: In this article, the authors define Orogenic Andesite and discuss its properties and properties, including the following: 1.1 Topography, gravity, heat flow, and conductivity.

An overview of adakite, tonalite–trondhjemite–granodiorite (TTG), and sanukitoid: relationships and some implications for crustal evolution
TL;DR: In this article, an analysis of an extensive adakite geochemical database identifies two distinct compositional groups: high-SiO2 adakites (HSA) which represent subducted basaltic slab-melts that have reacted with peridotite during ascent through mantle wedge and low-Si O 2 adakitic mantle wedge.

Orogenic gold deposits : A proposed classification in the context of their crustal distribution and relationship to other gold deposit types
TL;DR: The orogenic gold deposits were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens as discussed by the authors, with gold deposition from 15-20 km to the near surface environment.

Microfossils of the Early Archean Apex Chert: New Evidence of the Antiquity of Life
TL;DR: It is established that trichomic cyanobacterium-like microorganisms were extant and morphologically diverse at least as early as ∼3465 million years ago and suggests that oxygen-producing photoautotrophy may have already evolved by this early stage in biotic history.
